Mark Selby: Leicester cueman reached quarter-finals at the Crucible for the fifth time
Mark Selby became the first man into the World Championship quarter-finals with a 13-9 victory over Ali Carter, while Joe Perry leads defending champion Ronnie O'Sullivan 9-7 going into the final session of their second-round match.
Selby carried a 9-7 advantage into Friday evening and reeled off the first three frames to move within one of victory in the best-of-25 contest.
Carter delayed his exit by winning two in a row, including a run of 57, but Selby finished off his fellow Englishman in the next frame to book a last-eight meeting with either Alan McManus or Ken Doherty.
McManus moved 4-3 ahead of fellow veteran Doherty after a gruelling first session on Friday afternoon.
O'Sullivan still behind
Meanwhile Perry, leading 5-3 overnight, split the middle session four frames apiece with five-time world champion O'Sullivan and will resume at 10am on Saturday morning requiring four more frames for victory.
The damage could have been worse for O'Sullivan, with Perry missing a number of opportunities to go four clear by winning the final frame.
O'Sullivan, who has lifted the title at Crucible in each of the last two years, began brightly on Friday afternoon with a 93 break, only denied a century by going in-off on the black.
But the unflappable Perry restored his two-frame cushion with a break of 68 and went further ahead with runs of 48 and 46 in the 11th frame.
A missed red by Perry let O'Sullivan in for a break of 66 as he narrowed the gap to 7-5 and the Essex cueman got the better of a safety exchange in the next to move within one frame.
But just when it seemed O'Sullivan had hauled his way back into contention, Perry responded with two flawless back-to-back frames, breaks of 86 and 73 moving him three clear.
Perry had opportunities to make it 10-6 before O'Sullivan cleared from yellow to pink to bring an end to a lengthy frame and an engrossing session.
Walden leads Hawkins
Also on Friday, Ricky Walden opened a 9-7 advantage over Barry Hawkins in their second-round encounter, a repeat of last year's semi-final won by Hawkins.
Walden had breaks of 109 and 112 during a run of five frames in a row in the evening to power 9-5 in front.
But Hawkins took the last two with runs of 87 and 53 to revive his challenge. The match concludes on Saturday afternoon.
